Abstract (en)
[origin: WO2016069000A1] A method for generating a cement bond log, in some embodiments, comprises transmitting sonic or ultrasonic waves in multiple directions from a logging tool disposed in a wellbore, receiving reflected waves at the logging tool and recording waveforms based on the received waves, processing the waveforms to determine numerical values that indicate a degree of bonding associated with multiple portions of a cement sheath disposed in the wellbore, aggregating the numerical values, and generating a composite image based on the aggregated numerical values.
